faire le plot du nombre du boucle pour n assez grand ,le plot pour le nombre d'operation,le plot du temp d'execution

function i = pdga(n)
  factors = factor(n);
  if length(factors) == 1
    i = 1;
  else
    i = prod(factors(2:end));
  end
end

Approximate translation:

Make the plot of the number of loop for n large enough, and the plot for the number of operation, and the plot of execution time

[Walter Roberson]

That looks suspiciously like my code...
